Electronic device chassis

ABSTRACT

A chassis includes a board defining a number of openings, and a number of fixing members detachably mounted on the board. Each fixing member includes a fastener and a holding piece. The fastener includes a blocking portion and a post extending from the blocking portion. The post defines a slot adjacent to the blocking portion. The holding piece fits about the fastener in the slot. The fastener extends through a corresponding opening of the board. An outer side of the board blocks the blocking portion, and an inner side of the board blocks the holding piece.

BACKGROUND

1. Technical Field

The present disclosure relates to a chassis of an electronic device.

2. Description of Related Art

A circuit board is fixed to a computer chassis through a plurality ofsupporting posts. When there is a need to fix another circuit boardhaving a different size, the supporting posts should be replaced withother supporting posts. However, in most cases, the supporting posts areintegrally formed with the chassis, which can be difficult andinconvenient to replace.

DETAILED DESCRIPTION

The disclosure, including the accompanying drawings, is illustrated byway of example and not by way of limitation. It should be noted thatreferences to “an” or “one” embodiment in this disclosure are notnecessarily to the same embodiment, and such references mean at leastone.

Referring to FIG. 1 to FIG. 4, an exemplary embodiment of a chassis ofan electronic device, such as a computer, includes a board 10 and aplurality of fixing members 20 detachably mounted on the board 10.

A plurality of openings 12 is defined in the board 10. Each opening 12includes a bigger first through hole 120 and a smaller second throughhole 122 communicating with the first through hole 120. A substantiallyU-shaped extending portion 124 extends from an inner side bounding thesecond through hole 122.

Each fixing member 20 includes a fastener 22 and a holding piece 24. Thefastener 22 is substantially T-shaped, and includes a blocking portion220 and a post 222 extending from a center of the blocking portion 220.The post 222 axially defines a screw hole 224 extending through the post222 and the blocking portion 220 and defines two slots 226 in oppositesides of a circumference of the post 222, adjacent to the blockingportion 220. The holding piece 24 is substantially U-shaped, andincludes two opposite clips 240, with distal ends of the clips 240extending toward each other. A substantially wedge-shaped latch 242extends down from a center of the holding piece 24 opposite to the clips240.

In assembly, the clips 240 of the holding piece 24 are deformed to moveaway from each other, thus the holding piece 24 fits about the post 222of the fastener 22 in the slots 226. The clips 240 clamp the post 222 inthe slots 226, and the distal ends of the clips 240 resist against thepost 222. The blocking portion 220 of the fastener 22 extends throughthe first through hole 120 from an inner side of the board 10. Theholding piece 24 is attached to the inner side of the board 10. Thefastener 22 is moved to the second through hole 122 from the firstthrough hole 120. Therefore, the blocking porting 220 of the fastener 22is blocked by the extending portion 124, the latch 242 is blocked by theinner side bounding the first through hole 120 away from the secondthrough hole 122, to fix the fixing member 20 to the board 10.

When the fastener 22 needs to be replaced, the latch 242 is disengagedfrom the inner side bounding the first through hole 120. The fastener 22is moved to the first through hole 120; thereby the blocking portion 220of the fastener 22 can be easily removed from the first through hole120. The holding piece 24 is moved from the fastener 22 by deforming theclips 240 away from each other.

In other embodiments, in assembly, the post 222 of the fastener 22extends through the first through hole 120 from an outer side of theboard, until the slots 226 extend out of the first through hole 20. Thefastener 22 is moved to the second through hole 122 from the firstthrough hole 120. The blocking porting 220 of the fastener 22 is blockedby the extending portion 124 of the second through hole 122. The holdingpiece 24 fits about the post 222 in the slots 226. The latch 242 isengaged with the inner side bounding the first through hole 120.

It is believed that the present embodiments and their advantages will beunderstood from the foregoing description, and they will be apparentthat various changes may be made thereto without departing from thespirit and scope of the description or sacrificing all of their materialadvantages, the examples hereinbefore described merely being exemplaryembodiment.

1. A chassis of an electronic device, comprising: a board; and aplurality of fixing members, each fixing member comprising a fastenerand a holding piece, the fastener comprising a blocking portion and apost extending from the blocking portion, the post defining two slots inopposite sides of a circumference of the post adjacent to the blockingportion, the holding piece fitting about the post in the slots; whereinthe fastener extends through the board, the blocking portion is blockedby an outer side of the board, and the holding piece is blocked by aninner side of the board.
 2. The chassis of claim 1, wherein the boarddefines a plurality of openings, each opening comprises a bigger firstthrough hole and a smaller second through hole communicating with thefirst through hole, each fastener is capable of extending through thefirst through hole to be shifted to and received in the second throughhole.
